This is confusing and frustrating. In C++ we can write
MyInfos {

// one is a constant pointer to a constant object of type Obj
Obj const * const one;

}
And in main()
Info const * x1 = MyInfos.one;
x1 i a modifiable pointer to a constant object of type Info.
Is this possible in D ? I couldn't find how to do that.
I should have addressed this above. This is another of the those
things that will bite you if you are thinking in C++ when writing
D. Classes in D are references types, so right out of the gate
they can not be treated as C++ classes. You absolutely can have
modifiable pointers to const and immutable data with built in
types and structs, but not with classes. Always think of
const(classref) as const(class*). There is no such thing as
const(class)* in D.
